Demantoid Garnet
The history of Garnet dates back to the Bronze Age (more than 5,000 years
ago), when it was a very popular gemstone. According to Christian and Jewish
mythologies, when God's wrath clouded the earth with thunderous storms and
endless rain during the Great Flood, a radiant red Garnet guided the way
for Noah, ultimately leading his ark to salvation.

Unlike other gemstones, Garnets
are believed to contain both protective and destructive elements. The Crusaders
set Garnets into their body armor, believing the protective power of the
stones would lead them to safety. Conversely, some Asian cultures added
Garnets to bullets, believing its destructive power would greatly amplify
the enormity of a wound.
The name "Garnet" is believed to have derived from "pomegranate" with its
red, "Garnet colored" seeds. While the name Garnet has long been associated
with a rich red color, the gemstone actually comes in a much wider array
of color variations including: reds, oranges, greens and color change.
Garnets are found in a wide variety of locations
including: Kenya, Sri Lanka, Thailand, Brazil, India & Arizona (USA), however
the bulk of today's Garnet supplies come from Africa. When evaluating Garnets,
color is the most important characteristic. The color must be intense and
uniform with a tone that is not too light or too dark. Fine Garnets should
be eye clean with minimal inclusions under magnification. Size is also a
very critical determinant of the stone's value.
Garnets are a group of related minerals, containing
cubic crystalline structure with slight variations in their chemical compositions.
In all, there are 7 major types of Garnets, which include Almandine, Pyrope,
Spessartine, Grossular, Andradite, Rhodolite and Malaia.>
Andradite Garnets are undoubtedly one of the
rarest gemstones. The intense medium green variety, known as Demantoid,
is quite spectacular. Having the highest refractive index of all Garnets,
Demantoid's brilliance is second to none. The finest stones will contain
some inclusions, called "horse tail" inclusions, which are fibrous strands
of Byssolite. Other color varieties of
Andradite Garnets do exist, however their beauty is incomparable to the
stunning brilliance of Demantoids.
